All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise specified. 7. Supply current specification is valid for loaded drivers when DE = 0V. 8. Applies to peak current. See “Typical Performance Curves” starting on page 14 for more information. 9. When testing this parameter, keep RE = 0 to prevent the device from entering SHDN. 10. When testing this parameter, the RE signal high time must be short enough (typically <100ns) to prevent the device from entering SHDN. 11. Devices are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 50ns, the parts are guaranteed not to enter shutdown. If the inputs are in this state for at least 600ns (1200ns if VCC=1.8V), the parts are guaranteed to have entered shutdown. See “Low Power Shutdown Mode” on page 13. 12. Keep RE = VCC, and set the DE signal low time >600ns (1200ns if VCC=1.8V) to ensure that the device enters SHDN. 13. Set the RE signal high time >600ns (1200ns if VCC=1.8V) to ensure that the device enters SHDN. 14. If the Tx or Rx enable function isn’t needed, connect the enable pin to the appropriate supply (see “Pin Descriptions” on page 3). 15. Compliance to data sheet limits is assured by one or more methods: production test, characterization and/or design.
